Preheat the oven to 350°F (175°C).

In a bowl, whisk together flour, baking soda, and salt.

In a separate bowl, cream together softened butter, granulated sugar, brown sugar, and vanilla extract until smooth.

Beat in the eggs one at a time, mixing well after each addition.

Gradually blend the flour mixture into the creamed mixture.

Stir in the chocolate chips.

Spread the batter evenly into a greased baking pan.

Bake for 25 minutes or until a toothpick comes out clean.

Let cool before cutting into bars.
